PAPER-ROLL HOLDER AND CUTTER.

SPECIFICATION forming part of Letters Patent No. 417,592, dated December 17,1889.

Application Sled October 25,1888. Serial No. 289,121. (No model.)

To all whom it may concern:

Be it known that I, John B. Seymour, Jr., a citizen of the United States, residing at the city of St. Louis, State of Missouri, have in5 vented a certain new and useful Improvement in Paper-Roll Holders and Cutters, of which the following is a full, clear, and exact description.

My invention relates to an improvement in io that class of paper-roll holdersand cutters in which the cutter adjusts itself by gravity to the diminishing paper roll, and has for its' object to utilize the weight of the cutter-bar and the pressure produced thereon by cutting the 15 paper for binding and holding the paper roll, and to leave a sufficient length of paper exposed at all times after being cut for seizing and unwinding the paper roll for a fresh cut.

It consists in the use of a specially-shaped 20 cutter-bar mounted over and adjustable by its gravity to the diminishing paper roll, the lower edge of the bar opposite to its cuttingedge bearing upon the paper roll, while the cutting-edge is on top and removed from the 25 paper roll for cutting downward thereon instead of upward against, as heretofore.

On the accompanying drawings, Figure 1 represents a front elevation of my improved paper-roll holder and cutter; Figs. 2 and 3, a 30 side elevation and plan, respectively, thereof;

Fig. 4, a plan of the cutter-bar detached, to an enlarged scale; and Fig. 5, an end view of the same, like letters of reference denoting like parts in all the figures.

a represents the paper roll mounted on its spindle δ between the standards c, in the usual manner. From the front of each standard c projects a forwardly and upwardly inclined bracket d, through which from side to side is 40 a longitudinal slot e, the center line of which is preferably coincident with the axle b of the paper roll a. Between the side brackets d, which, with their slots e, are opposite to each other, is mounted transversely on the paper 45 roll a the cutter-bar/, having flattened ends g, with shoulders g', for sliding within the slots e as the bar/adjusts itself by gravity to the diminishing paper roll a. The cutter-bar f is specially shaped and arranged (seen more particularly in Figs. 4 and 5)-that is to say, its lower edge/', which is opposite to the cut ting-edge f², and preferably convex transversely, bears upon the circumference of the paper roll a, while the cutting-edge f² is on top and removed from the paper roll a, in lieu 55 of being adjacent to the line of contact between the latter and the cutter-bar. From the cutting-edge f² the cutter-bar f extends at a suitable inclination backward and downward to a suitable width on top, and thence 60 somewhat curved (or inclined) sharply downward at the back to the lower convex edge /'. Secured to the back of the cutter-bar /, but at a slight distance therefrom, is a longitudinal rod i, (see Figs. 4 and 5,) for supporting 65 the paper after being cut, as hereinafter more particularly referred to. The paper being unwound from the roll a is passed from the convex lower edge /' of the cutter-bar /, between the back of the latter and the rod i, 70 and thence across the top of the bar/to the required length for cutting. In cutting the paper its free end overhanging the cutter (see Figs. 2,3,4, and 5) is pressed from above upon the cutting-edge/², and the downward press- 75 ure thereby imparted to the cutter-bar / plus its own weight, presses upon and holds the paper roll while being cut. After being cut the free end of the paper, lying across the extended width of the top of the cutter-bar / 80 springs upward from the cutting-edge f², and, being prevented from falling back onto the paper roll a by the rod i, thereby allows the paper to be seized for unwinding from the roll a previous to another cut. By curving 85 the back of the cutter-bar /, as above described, the frictional resistance thereat to the passage of the paper from the roll a is reduced to a minimum.
